Title: Image display device and manufacture of this image display device
Inventor: HASHIMOTO HIROYUKI
IPC: H01J29/94
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To maintain a vacuum degree in a display panel, formed in a large area, in a sufficient level, by using fine powder of a non-evaporation getter and a mixture of an evaporation getter in a getter material. SOLUTION: In a getter material container 301, as a getter material, fine powder of a non-evaporation getter and a mixture of an evaporation getter are internally wrapped. Just before sealing or after sealing an envelope 88 constituted by a faceplate 86, rear plate 81 and a support frame 82, the getter material container 301 is heated, getter treating is performed. Thus by using the fine powder of the non-evaporation getter mixed in the evaporation getter, by concurrently using the non-evaporation getter having hydrogen exhaust power, a water molecular pressure particularly in a device is decreased, a non- evaporation getter material is dispersed over a wide range, fine powder of the non-evaporation getter is mixed, so as to enlarge the surface area of the dispersed getter material, gas adsorbing efficiency is improved.  Accordingly, a vacuum degree in the device can be maintained by these actions.

Title: Flexible channel allocation for cellular system based on hybrid of dynamic channel allocation algorithm based on measurement and reuse distance reference algorithm
Inventor: BORST SIMON C
IPC: H04W16/10
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To perform effective channel allocation by applying a reuse distance reference algorithm to a candidate channel list generated by a measurement based dynamic channel allocation MBDCA algorithm against a new call and selecting a channel corresponding to the new call. SOLUTION: A flexible channel allocation scheme is a hybrid algorithm and selects an optimum channel to be allocated to a cellular call based on a dynamic channel allocation MBDCA algorithm of a measurement base using an interference signal measurement value obtained in base stations 201 and 202, and on a reuse distance reference algorithm using information stored in a data base contained in a mobile object switching center MSC which performs switching between the mobile objects 203 and 204. In an MBDCA scheme, a channel is allocated to a call when the channel satisfies a prescribed call quality standard. The MBDCA scheme is applicable to both traffic and interference and more excellent in terms of the system capacity than a dynamic channel allocation scheme that is based only on a reuse distance reference.

Abstract: PURPOSE:To provide a method for controlling the oxygen concentration by which the oxygen concentration in a semiconductor single crystal is controlled so as to enable a wide range of control over the concentration of oxygen contained in a pulled up single crystal in producing a semiconductor single crystal according to the Czochralski (CZ) process. CONSTITUTION:This method for controlling the oxygen concentration of a semiconductor single crystal is to extend the length in the axial direction of a heater 6 and a heat insulating cylinder 7 downward as shown in the left half of figure 1 so as to control the oxygen concentration to a rather high value and increase heat reserving properties in the lower part in a furnace or extend the heater 6 and heat insulating cylinder 7 downward and further attach a heat insulating material 10 in the lower part of the heater composed of a heat insulating material to the top surface of the heat insulating material 8 in the lower part of a chamber and enhance the heat reserving properties in the lower part of the furnace. Otherwise, the installation height of a graphite member in the furnace may be lowered to thereby contract the volume below the heater. In this state, the heat insulating material 10 in the lower part of the heater may further be attached thereto. The thickness of the heat insulating material 8 in the lower part of the chamber is reduced so as to control the oxygen concentration to a rather low value.

Title: Flat organic electrolyte cell
Inventor: OGURO HIDESUKE
IPC: H01M4/06
Filed: 1985-03-20
Abstract: PURPOSE:To aim at reducing dispersion in internal resistance before discharging of a cell by forming notches like a comb in the bottom of a ring, that is, the part lying between a case and a positive electrode. CONSTITUTION:This is concerned with a flat organic electrolyte cell which uses a light metal such as lithium as an active material for a negative electrode and has a ring 7 with a section like a L character, whose edge lies between a case 3 and a positive electrode 1, thereby the ring 7 is provided with a central hole 8 radial notches 9 like a comb. the cause of dispersion in internal resistance of a cell when it is not yet discharged, is generated due to bad electrical contact between the ring and the positive electrode at the bottom of the ring. It is the best method to force the circumference of the metal ring to cut into the positive electrode, in order to improve electrical contact between the metal ring and the positive electrode formed by pressure molding powder. This means, by using a ring having a section like an L character as well as notches like a comb at its bottom, it becomes possible that dispersion in internal resistance of a flat organic electrolyte cell is reduced, and internal resistance at the time of discharging gets stabilized.

Abstract: PURPOSE: To detect in a reliable manner the rubbing by taking the corelationship between the vibration data of a stationary body and the vibration data of the same when the rubbing vibrations take place so that the occurence of the rubbing is judged if the corelationship corresponds to the generation of the rubbing vibrations.  
     CONSTITUTION: A plurality of vibrators 6 are attached to the shaft packing 5 of a turbine 1 and a generator 2, and the vibrations generated are selected by means of a data selector 7 so that N data are recorded at a suitable time interval by means of a data recorder 8. The mean value is obtained by its calculator 9 whereas the dispersion is obtained by its calculator 10. A comparison data generator 13 is stored with the data, mean value and dispersion which are obtained during the rubbing occurence by the similar processing. The phase relationship calculator 11 calculates the corelationship coefficient from the two values. A comparator 12 compares this coefficient with the preset coefficient thereby to feed signals to an output dievice 15 if the former is higher than the latter. The device 15 responds to the signals to inform the rubbing occurence.

Abstract: PURPOSE:To prevent dislocation in a vertical direction on a television screen even when an omission exists in a vertical synchronizing signal part by discriminating the omission of a part corresponding to the vertical synchronizing signal and switching a signal showing a write reference. CONSTITUTION:A vertical synchronization separation circuit 2 separates the vertical synchronizing signal from a reproduced video signal (b). A write reference generation circuit 3 generates the write reference signal (c) based on the signal and outputs it to a switch 5. A flywheel oscillation circuit 6 generates a pseudo vertical synchronizing signal by counting a horizontal synchronizing signal for one field with the vertical synchronizing signal of the reproduced video signal as the reference, generates a write reference signal (d) based on the signal in a write reference generation circuit 7 and outputs it to the switch 5. The horizontal synchronizing signal generated by using the different flywheel oscillation circuit based on the horizontal synchronizing signal of the reproduced video signal is used and therefore influence by the omission of the horizontal synchronizing signal owing to drop-out can be eliminated.
